x86: Timing support for pagetable walker
...
Move page table walker state to its own object type, and make the
walker instantiate state for each outstanding walk. By storing the
states in a queue, the walker is able to handle multiple outstanding
timing requests. Note that functional walks use separate state
elements.

Fault: Rename sim/fault.hh to fault_fwd.hh to distinguish it from faults.hh.

Faults: Pass the StaticInst involved, if any, to a Fault's invoke method.
...
Also move the "Fault" reference counted pointer type into a separate file,
sim/fault.hh. It would be better to name this less similarly to sim/faults.hh
to reduce confusion, but fault.hh matches the name of the type. We could change
Fault to FaultPtr to match other pointer types, and then changing the name of
the file would make more sense.

This is to help tidy up arch/x86. These files should not be used external to
